The AdoDotNetObjectEnumerator type exposes the following members.

Constructors

	Name	Description

Properties

	Name	Description
	Connection	Retrieves the current data connection. (Inherited from DataObjectEnumerator.)
	Site	Retrieves or sets the object site. (Inherited from ObjectWithSite.)

Methods

	Name	Description
	EnumerateObjects	Enumerates items for a set of data objects of the specified type with the specified restrictions and sort string, if supported. (Overrides DataObjectEnumerator.EnumerateObjects(String, array<Object[], array<Object[], String, array<Object[]).)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnSiteChanged	Raises the SiteChanged event. (Inherited from ObjectWithSite.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Events

	Name	Description
	SiteChanged	Event that is raised when the Site property is changed. (Inherited from ObjectWithSite.)

Top

Explicit Interface Implementations

	Name	Description
	IObjectWithSite.GetSite	Retrieves the last site set using the IObjectWithSite.SetSite method. In cases where there is no known site, the object returns an exception. (Inherited from ObjectWithSite.)
	IObjectWithSite.SetSite	Provides the site's pointer to the site object. (Inherited from ObjectWithSite.)

Remarks

It is not expected that a data provider based on ADO.NET will need to customize object enumeration. However, this class provides a managed base class that can be extended in case extra or modified enumeration functionality is required inside Visual Studio.

The EnumerateObjects method takes in its parameter array a single string that specifies the name of the ADO.NET schema collection to enumerate.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
